[PKG SUPPORT] `pylint <3` and Python 3.12

[valeriupredoi]

Hey fellas, a quick touching base from one of your conda-feedstock maintainers here - the new v1.10.3 builds well now https://github.com/conda-forge/prospector-feedstock/pull/43 - but I had to pin upper pylint to <3, see failed test with pylint=3 - and since I vaguely understand poetry environment files, I wanted to double check pylint is upper pinned to <3 upstream (here) too. Incidentally, Python 3.12 support seems to work fine for you, so I'd suggest you included a Github Action test for 3.12 as well (seen you guys have them all Pythons but no 3.12 GA test yet). Cheers and keep up the good work :beer:
